Hi Perderabo,
this is sun box running solaris 8.few days back a file system was full.
i had made space in it..but it didn't work out.
Actually,it was not FS problem...bcoz when i observed ,i found that system was running on very low memory ( hardly 200 MB real) ,so i guess only root was allowed.
I killed few sessions;brought down my databse;& re-booted machine.
now i hav almost 7GB real memory free after reboot,so its working now.
Idea of rebooting was the first to struck at my mind..but that ,i guess,could not be a solution all time.
my worry was where all memory was getting used?
bcoz most of the processes were run by root itself..( daemon etc..)
thanks for your suggestion,
regards
Abhijeet

systemd-volatile-root.service
SYSTEMD-VOLATILE-ROOT.SERVICE(8) systemd-volatile-root.service SYSTEMD-VOLATILE-ROOT.SERVICE(8)
NAME
systemd-volatile-root.service, systemd-volatile-root - Make the root file system volatile
SYNOPSIS
systemd-volatile-root.service
/lib/systemd/systemd-volatile-root
DESCRIPTION
systemd-volatile-root.service is a service that replaces the root directory with a volatile memory file system ("tmpfs"), mounting the
original (non-volatile) /usr inside it read-only. This way, vendor data from /usr is available as usual, but all configuration data in
/etc, all state data in /var and all other resources stored directly under the root directory are reset on boot and lost at shutdown,
enabling fully stateless systems.
This service is only enabled if full volatile mode is selected, for example by specifying "systemd.volatile=yes" on the kernel command
line. This service runs only in the initial RAM disk ("initrd"), before the system transitions to the host's root directory. Note that this
service is not used if "systemd.volatile=state" is used, as in that mode the root directory is non-volatile.
